The Eucumbene River, a perennial river of the Snowy River catchment, is located in the Snowy Mountains region of New South Wales, Australia.

Course and features

The Eucumbene River rises below Shaw Hill, in the northern part of the Kosciuszko National Park, approximately north of the village of Kiandra. The river flows generally south and southeast before emptying into Lake Eucumbene, where its flow is impounded by Eucumbene Dam. After passing through or over the dam wall, the river flows generally south before emptying into Lake Jindabyne, impounded by Jindabyne Dam. Within Lake Jindabyne, the river reaches its confluence with the Snowy River.

The river descends over its course, joined by seven minor tributaries.
